Since Susan's charges are directly proportional to the number of children she is watching, we can set up a ratio to find her rate per child.
Given that Susan charges $4.50 for 3 kids, we can find her charge per child:
\[
\text{Charge per child} = \frac{\$4.50}{3} = \$1.50
\]
Now, to find out how much she would charge for 5 kids, we multiply the charge per child by the number of kids:
\[
\text{Charge for 5 kids} = 5 \times \$1.50 = \$7.50
\]
So, Susan would charge **$7.50** to babysit 5 kids.
